There is a lack of consensus about whether the initial imaging method for patients with suspected nephrolithiasis should be computed tomography (CT) or ultrasonography.1
Although renal colic in children in the United States remains relatively uncommon compared to in adults, its incidence has nearly doubled from 1999 to 2008. Noncontrast computed tomography (CT) is the current standard for the evaluation of suspected renal colic, given its high sensitivity and specificity. However, the greater lifetime risk of radiation-induced cancer from CT in pediatric patients has led to efforts to minimize radiation exposure. Additionally, pediatric renal colic is often recurrent, which might require multiple imaging studies during their lifetime. Point-of-care ultrasound (POCUS) by emergency physicians avoids radiation, has a low marginal cost, can be performed concurrently with other management,

In chronic diseases such as urolithiasis, efforts are made to limit radiation exposure, particularly for routine surveillance. We sought to determine the correlation of ultrasonography (US) compared with noncontrast CT (NCCT) in detecting and determining size of stones.3
The usefulness of ultrasound colour-Doppler twinkling artefact for detecting urolithiasis compared with low dose nonenhanced computerized tomography.4
This study was conducted to assess the diagnostic yield of B-Mode Ultrasonography compared to unenhanced helical CT scan in detecting urinary stones in patients with acute renal colic.5
Our aim was to evaluate the effectiveness of twinkling artifacts (TA) in detecting calculi <5 mm in diameter in patients with renal colic pain who had undergone urinary grayscale ultrasonography (US) and computed tomography (CT) imaging assays.6
The aim of our study was to compare non-contrast spiral CT, US and intravenous urography (IVU) in the evaluation of patients with renal colic for the diagnosis of ureteral calculi.
